One Piece 21 features story and art by Eiichiro Oda.

The Straw Hats are keeping the Officer Agents preoccupied while Vivi makes her way to the palace. Sanji's got his hands full with Mr. 2 Bon Clay while Zolo battles mano a mano with Mr. 1 - or rather sword to sword body in this case! That leaves Nami on her own with Ms. Doublefinger - a prickly predicament with only her wits and Usopp's special weapon to depend on. Can the Straw Hats prevail against the best of the Baroque Works?!
